    Kelviq▲530

    Hi HN, We've been building Kelviq for the last couple of months and it's finally ready to share. Kelviq is a Merchant of Record (MoR) and monetization platform that you can integrate without building a custom webhook-to-database syncing layer. Along with handling global taxes, checkout, and compliance, it acts as the real-time source of truth for your users feature access and usage credit balances. Why we built this: Through our other project, ParityDeals, we saw firsthand how much founders struggle with billing infrastructure. Integrating a payment gateway is easy, but actually building…

    Stripe is great, but is not simple. You end up handling many webhooks, mirroring Stripe data, tracking subscription states, and hardcoding feature checks. Managing upgrades, downgrades, migrations, overrides, and grandfathering often needs custom scripts. ParityDeals keeps that billing logic out of your app. Once you integrate ParityDeals SDK, you can manage everything from a single dashboard. No further code changes required. I'd love to hear your feedback

    Credyt▲100

    Hey HN! I'm the founder of Credyt (https://credyt.ai). If you're running an AI product that burns $0.50+ per interaction, you need to bill customers as usage happens, not at the end of the month. Otherwise you're a bank for your customers, and you'll run out of money before they do. Why invoice-based billing doesn't work for AI: Most usage-based billing tools (Stripe Billing, Orb, etc.) were built for SaaS. They meter usage all month, then send an invoice. That works fine when your COGS is 5%. It's a disaster when you're paying your AI vendor upfront for every request and your…
